Question

the mean of x+3, x-2, x+5, x+7and x+72 is ​

Answer 1

Answer:

x+17

Step-by-step explanation:

MEAN = (x+3+x-2+x+5+x+7+x+72)/5

= (5x+85)/5

= 5(x+17)/5

= x+17

Answer 2

$:\implies\sf M = \dfrac{x+3 + x - 2 + x + 5 + x + 7 + x + 72}{5}\\\\\\:\implies\sf\dfrac{5x+85}{5} \\\\\\:\implies\sf M = \dfrac{\cancel{\;5}\;(x + 17)}{\cancel{\;5}}\\\\\\:\implies\sf\pink{M = x + 17}$

•°• Hence, the required Mean is x + 17.
